The Godfather made Al Pacino a star, setting him on a path toward one of the most singular and inimitable careers in Hollywood history. It was also so difficult for the actor to make that he was nearly fired multiple times.

In his new memoir, "Sonny Boy," Al Pacino wrote that he and Diane Keaton were certain that "The Godfather" would end their burgeoning careers.

The Godfather trilogy may consist of three movies, but Francis Ford Coppola doesnt consider the series to be a true trilogy for one simple reason.
